Associate Professor of Nanoparticle Physics and Surface Chemistry. B.Sc. in theoretical physics, Ph.D. in physical chemistry, Docent in atmospheric physics. Passionate about thermodynamics of environmental systems in all shapes and forms, from soap molecules on the surfaces of cloud droplets to nano-inclusions in rocks and solids, salt clusters in space, and alcohols in the sap of trees. Specializes in aerosol and surface thermodynamics and cloud microphysics. Always on the lookout for novel methods to advance our understanding of the Earth system, environment, and space. Currently leading projects related to development and application of synchrotron radiation excited spectroscopy in atmospheric chemistry and climate change (ERC StG SURFACE), new thermodynamics tools for understanding aerosol and cloud formation (Academy of Finland Fellowship SURFACE-IMPACT), and machine learning and artificial intelligence to reduce traffic related air pollution (Academy of Finland project ANTHRO-IMPACT).
